Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Williamtown
Flood
Williamtown is susceptible to flooding due to its proximity to the Hunter River and low-lying areas. Increased rainfall intensity could exacerbate flood risks.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The area surrounding Williamtown has bushland, increasing the risk of bushfires, especially during dry periods. Climate change is expected to lengthen the fire season and increase fire intensity.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Williamtown is projected to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations and infrastructure.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Located near the coast, Williamtown faces risks from sea level rise and coastal erosion. These factors could impact infrastructure and property values.
Key drivers:
- ·Sea level rise
- ·Increased storm surge

What This Means for Property Owners
Insurance Outlook
Premiums are likely to increase due to the rising risks of flooding, bushfires, and coastal erosion.
Price Impact
Properties in high-risk areas may experience a decrease in value due to climate change impacts.
Buyer Checklist
- 1.Check flood maps and bushfire prone area designations.
- 2.Assess the property's vulnerability to sea level rise and coastal erosion.
- 3.Inquire about insurance costs and coverage for climate-related risks.
- 4.Consider the property's energy efficiency and ability to withstand extreme weather events.
How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout Williamtown's Climate Risk Profile
Williamtown, located in the Hunter region of New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to the Hunter River and coastal areas makes it particularly susceptible to flooding and sea level rise.
Rising temperatures and drier conditions are expected to increase the risk of bushfires in the surrounding areas. Heatwaves are also projected to become more frequent and intense, posing a significant threat to public health, especially for vulnerable populations.
Flooding is a major concern, with potential for increased rainfall intensity to overwhelm existing drainage infrastructure. Sea level rise could exacerbate coastal erosion and inundation, impacting property values and infrastructure.
Addressing these challenges requires a coordinated effort involving local government, emergency services, and the community. Adaptation measures, such as improved drainage, bushfire mitigation strategies, and heatwave preparedness plans, are essential to protect the suburb and its residents.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
